ToImage provides the IDL data catcher user with a method of
re-constructing the 2D images if the images did not get saved during
2D scan. At the normal operation of the data catcher user never
needs to run this program. The 2D images are automatically saved
at the end of 2D scan. Only when the 2D scan obnormally terminated
during the 2D scan such as workstation died or rebooted during the 2D scan.

Warning:

A user should never use this program while the scan is going on.
A user never need to run this program unless absolutely necessary to
reconstruct a new 2D image file due to system went down during 2D scan.

I recommand that the user always preview the image first before
append the images to an output file. For data integrity, a user
better create new image files in a different directory instead
of the original data directory.

UNIX SYSTEM

To access the toImage program on Unix system just enter the following
command on the Unix prompt:
toimage
The complete system consists of two components: toimage and
toImage.pro.
toimage - a unix script file, it automatically sets up the IDL
and runs the IDL toImage.pro.
toImage.pro - an IDL widget application, it reads 1D scans and
reconstruct 2D images according to entered 1D scan range.
It calls the data catcher program to let the user
examining the 1D scans to figure out the range of 1D scans
which corresponds to a given 2D scan.

A user has to make sure that the same input 1D file is opened by the
toImage and catcher respectively.

USER INTERFACE

File - uses the file selection dialog to select a 1D catcher data
which can be native / XDR binary format
BIN/XDR - droplist shows the binary type of the picked file
Infile - text field shows the file name picked / entered
Y-PV - optional text field shows the Y scan name
Start # - 1D scan # at y(0) for a given 2D scan starts
When this field is entered with the the droplist
of Images will be changed to ViewOnly again to let the
user preview the image first. If a user wants to save the
image to the output file, he/she has to explicitly reselect
the Append / CreateNew option
End # - 1D scan # for a given 2D scan ends
Images: ViewOnly/Append/CreateNew - droplist shows the image mode
ViewOnly - only show 2D TV images of each detector
extracted from the input file
Append - show 2D TV images and append the images
to the outfile
CreateNew - show 2D TV images and create/append the images
to the outfile
Merge: No/Yes - droplist determines whether 2D scans to be merged
No - Only one 2D scan allows
Yes - Merge multiple 2D scans images into one single image
Out Image File - enter the output image file name, the name will
be automatically appended by the suffix '.image'.
The user is responsible for the uniqueness and
integrity of the file entered
Accept - depending on the image mode selected, it reads 1D data,
displays 2D images, saves the image file accordingly
Cancel - close the toImage program
